Quick Answer

Start with the target device, port, link distance, fiber type and document needs. Then use the article content below to narrow the model path before sending an RFQ.

If we want to understand the main differences between SFP-10G-SR and SFP-10G-LR, we need to know what SFP-10G-SR and SFP-10G-LR are. SFP-10G-SR in "SR" "meaning (short range), Wavelength of 850, belonging to the short wavelength, is a multi-die module Transmission distance of 2 ~ 300m, The advantages of this product is: the lowest cost, lowest power consumption and smallest fiber optic modules, etc. SFP-0G-LR in the "LR" refers to the Long Range The wavelength is 1310nm, which belongs to long wave and is a single mode module. The transmission distance is 2m to 10km and the maximum distance is 25km. Features of SFP-10G-LR: miniaturization, low power consumption and long transmission distance Combined with the above product description, Fiberland Co., Ltd. will compare the differences between the two to facilitate the choice of customers. Different transmission distances The SFP-10G-SR is used for short-distance transmission. Its wavelength is 850, the distance is 2~300m, and the farthest transmission is 300m. The SFP-10G-LR optical module is used for long-distance transmission, the wavelength is: 1310nm, the transmission distance is 2~10km, and the maximum transmission limit is 25km. But they have a common characteristic is not able to support the FCOE link path. We need to choose the right product according to the different transmission requirements The SFP-10G-SR and SFP-10G-LR lasers are different. The most common is laser optical communications lasers FP and DFB lasers. SFP-10G-SR uses VCSEL, 850 wavelength laser, emitting optical power between -6~-1dBm, sensitivity <-11.1dBm The SFP-10G-LR uses a laser that is DFB with a wavelength of 1310 nm. The transmitted optical power is -8.2~0.5dBm and the sensitivity is <-14.4dBm. The cost budgets of SFP-10G-SR and SFP-10G-LR are different. SFP-10G-SR price lower than the SFP-10G-LR price. Because the SFP-10G-LR optical module has a higher cost than the VCSEL laser due to the built-in DFB laser, the performance of the DFB is better. In summary, we should purchase the optical module in combination with the transmission distance and performance. If you have any demand for the product, please feel free to consult Fiberland company。
